Deleting Data From Production Sever
Jan 9, 2008
Hi All,
I have to delete 135 Million records from our production server, keeping only last three months data & the table doesnot have any index.
Can you please suggest the best possible approach to perform this activity.
Approach i am thinking :-
1)I will rename the existing table & create a new table with the same name (By this my application wont be interrupted)
2)then i am planning to create a nonclustered index on the date column sort order desc so that i can get the last three months data.
3)Once the index is created i can transfer the required records to the new table created in step 1.
Please sugeest your valuable feedback or suggestions to perform the task ASAP.
Thanks

I have been testing my database application for a while now. As a result i have a lot of records already with their respective identity field values. What i want to do is to reset this field to 0 (zero) before i deploy the aplication. I have tried deleting all the records and entered one to see if the id will be 1 but it still starts from where it was before i deleted the records. Any ideas.

Hi all,
I am having a problem with exporting the data. I have a database in SQL Server which has to be exported in to an ingres database. I was sure that there is no direct option to export the data to ingres, So I tried generating the insert script and cvs files. But the database consists of blobs and images which is not allowing me to create the complete insert script or cvs files.
Does any one know how to resolve this issue?
Thanks in advance,
Vamshi Shekhar C

Hello All
Just wondered if someone could help me with a bit of T-SQL, i have a application in ASP.NET/VB that allows the user to update a message board by clicking a button "update" this in turn triggers my Stored Procedure for inserting this data into a table, which works great.
It inserts the data into its respective fields and also takes The Title, Line 1, Line 2 and so on and creates a XML file (Using FOR XML) which is stored in the same Table under a column call XML_Data. Which again works great.
My problem now is how do i output this XML_Data to an actual XML file that is on my local machine, i.e. It be created in say C:Inetpubwwwrootxmlfiles("xml file name inserted here from another column that holds xml file name").xml
Any help on this would be greatfully apreciated
Thanks In Advance
Neil

I am trying to delete tables from data where the ModifiedDates older than 9 years in AdventureWorks2012 database . I get console notified that foreign keys are dropped but the delete statement is throwing errors. I am sure that somewhere the key constraints are not getting altered, but i'm not able to figure it out as i'm a relative beginner to T-SQL. The error and code:
The DELETE statement conflicted with the REFERENCE constraint "FK_SalesOrderHeaderSalesReason_SalesReason_SalesReasonID". The conflict
occurred in database "AdventureWorks2012", table "Sales.SalesOrderHeader
[System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.SMO") | Out-Null
$option_drop = new-object Microsoft.SqlServer.Management.Smo.ScriptingOptions;
$option_drop.ScriptDrops = $true;

I don't know if the question has been nailed down. Aside from deleting tables, can we delete the *content* of data within the tables. It doesn't seem crazy that, if you can pull in data from a feed then you should be able to remove the content out again (without also destroying the user's meta-data work ). Reasons for this include:
- Security (a user may not have rights to see *my* data and should go refresh their own)
- Size (workbook doesn't need to have GB's of irrelevant data saved to disk in a workbook if it was just useful during development phase to a pre-production data feed)
- Bad data (pre-production data feed is not good data)
- User-friendliness (data feed was refreshed 2 years ago and workbook was saved to file server. Users shouldn't be presented with irrelevant data, but should get empty pivot tables until they go do their refresh)
Obviously Excel internally knows how to clear out PowerPivot data, given the prompt shown here: [URL] ....
But how does a user initiate this on their own (corruption aside)?
Previous time this question was asked, without a real resolution: [URL] ....

This is probably an easy solution for some of you seasoned DBA Vets but here is my problem.
I have to take production data and scramble certain sensitive columns such as SSN, DOB, Address, First Name so that our Management team can use it as demo material. Is there a quick solution to this issue?
Thanks,

I'd like to move data from my prod. env. to my dev. env. The data in dev would be replaced by the prod one. I cannot do a detach/attach or backup and restore due to some already existing dev objects located in the dev. env.
Any lead on how I can do this?
Thanks Marcel

We are running SQL Server 2005 express on Windows 2003. The database server gets significant amounts of data.
Because of the 4GB data limit we have a daily cron task which goes through and deletes data older then 90 days.
We would like a way to archive this data instead of deleting it. Is there any way to take data and compress it and store it in a different way, so that if needed, customers can query directly out from the compressed data? Cleary querying from compressed would be slower but that is ok.
Any other solutions that would allow us to archive data instead of deleting it? Thanks.

Hello All,I have been searching for a published document for Best Practicesconcerning access levels based on roles. Should developers have morethan (if at all) select level access to production data? If Iunderstand (from multiple postings) that it is best to have:1. Development (developers have extensive access levels)2. Test (developers have restriced access levels)and3. Production (developers have none or select level access)Our environment and budget only allows for items 1 and 3.If any body could point me to a document from a 'reputable' source, Iwould greatly appreciate it.TIABill

I have a package which loads data from a flat file (csv) to 4 tables in a database.
Now, the load is incremental.
I want to clear the data of all 4 tables(in the database) before loading the data from flat file everytime.How can i do this?
Iam using 4 Oledb Destinations, 1 multicast, 1 source component to do this.
Also can it happen like a transaction? because if it deletes the existing data and couldnt load new data there will be a problem!.how to avoid this?

Here is my requirement.
There is a production database which has ever increasing data. For testing purposes though, I would like to build a test database with exactly the same schema but only a subset of data copied from the production database . I'll specify the criteria (something like a where clause in select query) for copying the data from the production database.
Is there a tool that anyone has come across to do this job ?

Hello,
I am trying to refresh a test database with data from a production database. Both database structures are identical, e.g. constraints, stored procs, PK, etc. I am trying to create a package in SSIS that accomplishes this task and I am having extensive problems. The import export wizard is out of the question because the constaints are not carried over, plus when I try to refresh the data using the import export wizard, it fails on 1 specific table because of a column in that table named "Error code". I think "Error code" is a micrsoft keyword, so it fails on this column. Does anyone know a workaround that I can do to accomplish this simple task, that could be completed in minutes using DTS. I understand that SSIS is not as straight forward as DTS, but this task is something that DBA's do on a regular basis and therefore should not be this difficult.
Any help would be appreciated,
David

I have question regarding SQL Transactional Replication methodology
1. Let's say successfully created SQL Transactional Replication and running / transferring data from publisher to subscriber
2. Now one day the source production / publisher SQL Server is down and the remaining DR SQL Server is up (subscriber)
3. Next day, we fixed and bring up the production / publisher SQL Transactional Replication server, then how can we sync back all existing data records from subscriber into publisher side ?

I have edited the aspnet_Users_CreateUser stored procedure so that the UserId that is created when a new user is created is copied to a UserId field in another table. However, when I use the website administration tool to delete users that have been created, it gives me an error saying the delete statement conflicted with the reference constraint. I then added the following code in the aspnet_Users_DeleteUser procedure....
IF ((@TablesToDeleteFrom & 16) <> 0 AND
(EXISTS (SELECT name FROM sysobjects WHERE (name = N'vw_tt') AND (type = 'V'))))
BEGIN
DELETE FROM dbo.userclassset WHERE @UserId = UserId
SELECT @ErrorCode = @@ERROR,
@RowCount = @@ROWCOUNT
IF( @ErrorCode <> 0 )
GOTO Cleanup
IF (@RowCount <> 0)
SELECT @NumTablesDeletedFrom = @NumTablesDeletedFrom + 1 hdhd
END
This code was then added to the function at the end which deletes the data from the aspnet_Users table when everything else has been removed
(@TablesToDeleteFrom & 16) <> 0 AND
Now when I delete a user in the website admin tool, it "deletes" (with no error) the user from the list but doesnt actually physically delete it from the database.
Any ideas?

I have added a delete button to my datagrid, and put in what I think is the code to delete a member from the database at their Member ID, however when I have called a members details and the delete button is pressed, nothing happens!!??
Any ideas?

I setup data collection on a production server to capture growth rates.
When I run the dis usage report, it shows a daily growth rate of over 500 megs. This seems excessive to me.
As a troubleshooting step I then ran sp_space used and got these results:
database_namedatabase_sizeunallocated space
rgc_prod 273442.63 MB3648.48 MB
reserved data index_size unused
265345488 KB164385384 KB99826072 KB1134032 KB
What should my next steps be to try and determine why there is so much growth? And isn't the index size rather large?
